The answer to this question is A.
The correct answer for this problem is C.) reflection across y=x .
Answer:
Step-by-step explanation:
VC = (1/3)·pi·r2·h
VC = volume of a cone
r = radius of base of cone = 6 cm
h = height
VC = (1/3)·pi·62·h
VC = 12·pi·h
VS = (4/3)·pi·r3
VS = volume of a sphere
r = radius of base of sphere = 3 cm
VS = (4/3)·pi·33
VS = 36·pi
Since the volume of the cone and the sphere are equal:
VC = VS
12·pi·h = 36·pi
Solve for h.
Answer: 2/3
(7/9) (18/21)
(7/9) (6/7)
common factor is 3 between 18 and 21. 7 x 3 = 21 and 6 x 3 = 18
7/9 6/7 multiply 7 x 9 = 63 and 6 x 7 = 42
= 42/63
= 2/3
decimal: 0.666667
